Just wondering if anyone out there has fitted a cummins to their Nissan patrol as in 6bt or 4 bt , done in the us . The chev duramax kits are common here ,not interested in that tho , just checkin , albo.

Cheers Robert , I havnt seen that one . lots of checking il do there .Thanks peter also , the chev sounds great , but iv heard mixed reports , expensive , overheating etc . I like my Nissan coil cab ute & iv had a fair bit to do with the cummins 4bt , 6bt & I was mainly interested if someone out there fitted a 4 bt , would make the perfect bush ute , cheap fuel ,easy riding . cheers albo

I've had a chevvy 6.5 normally aspirated diesel in my 75 series Troopy for 15 years now & it has never missed a beat. Fitted with a triple bi-pass radiator have travelled through some rugged remote areas of Australia in the middle of summer periods & never had overheating problems.It was one of the first fitted by Brunswick Diesels & at that time was cheaper then fitting a recon long motor to replace the existing 1HZ which had cylinder wear problems.I do agree that they are expensive to fit these days!!!!!!!

Thanks Ted , just toying ideas , id love to treat my ol faithful patrol coil cab ute a 4 bt cummins mate , I love it New vehicles these days involves too much electronics which is ok for city people , but im old skool ,always will be ...Never been towed home , always sorted myself out of trouble , If you upgrade to the electronic stuff I feel a loss of independence , imagine out the back of shts ville & your fuel tank gets a gut full of water in the fuel , are & the story can go down hil fast from there !

Hi Albo,Thats what I like about the chevvy. No fancy electronics when something goes wrong.I have heard of a few people putting Perkins diesels in their 4B's similar to the ones fitted in the early model Okkas but don't have any details of how they went.

Cheers Tomcat , the only ones Iv heard of in west oz were the Bantick brothers that did some cummins conversions in Kal but theve moved to Perth & there phone number doesn't work any more ,thanks anyhow mate ,albo.

I've been the AM General warranty agent for the original Hummer since 1996. The Hummer engine (GM 6.5L) is very reliable. The NA engine is really noisy but totally trouble free. The only warranty problems in all these years relate to an overloaded oil pressure switch that fails after time. I have a very quick, cheap and easy fix for it but when it worked into sales I didn't fix too many. The problem is that the oil pressure switch supplies the power to run the fuel lift pump and the fuel changeover valve and it simply fails after too much work. When the oil pressure switch fails there's no lift pump and the engine stalls intermittently. It already has a fuel pump relay but it is only triggered while cranking to start. The easy fix is to trigger the relay with the power supplied from the oil pressure switch. It needs a diode as well but the stalling problem is cured for life.

The turbo engine has pump problems. The only fix needed is to do away with the electronic fuel pump and crank up the manual pump that's fitted to the NA engine.

I wouldn't suggest buying a Brunswick Diesel as many of these are rebuilt on the cheap locally and they are simply not worth it. These engines are not expensive brand new and there is a good supplier in Victoria. We've supplied these new with better than 300hp coupled to the 5 or 6 speed Allison transmission. I've never see one broken.

Overheating is only a problem because people expect the cooling system from a 4L to cool the 6.5. It's simply too small.
